Abstract: 42,497 CAN 4A                            ABSTRACT           This invention is concerned with materials for nonlinear optical devices for the conversion of optical energy at one frequency to optical. energy at another frequency.  Laser techniques have been developed to a great extent and it is possible to obtain various kinds of laser light by utilizing solid, gas, and liquid media.  Laser light having various wavelengths is often desired and in some cases, a laser tight exhibiting a continuous spectrum over a certain range of wavelengths is desired.  One means for converting coherent laser light of a fundamental frequency into laser light of a wavelength having a frequency twice the fundamental frequency (i.e., the second harmonic) involves passing the laser light through a nonlinear optical crystal.         This invention involves devices for and method of generating coherent second harmonic light radiation.  The devices comprise a laser source of coherent light radiation at a fixed fundamental frequency, crystalline 5-chloro-2-nitroaniline that crystallizes in a non-centrosymmetric configuration, means for directing the output radiation of the laser onto the 5-chloro-2-nitroaniline, and output means for utilizing the second harmonic frequency.

Abstract: AN INTRINSIC PERCEPTUAL MOTOR TRAINING DEVICE             ABSTRACT         A perceptual motor training device uses a non-tactile method of training a patient who has suffered some interruption of his neurological functions to recognize the spatial position and orientation of his body and/or the parts thereof.  The device includes an alarm that is activated when a portion of the patient's body moves out of a predetermined test area.  The alarm alerts the patient without touching the patient so the patient is forced to use his own internal systems to determine the location and orientation of his body and the parts thereof.  The test area is defined by beams and/or fields and can include test areas within the overall test area.  The device can also be used in conjunction with the  training of  gross motor  developmental sequences as well.

Abstract: ABSTRACT OF THE DISCLOSURE           A valvulotome for rendering venous valve leaflets incompetent includes a rigid support comprising a fluid supply tube and, molded thereon, a dilator, and first and second valve disrupting heads.   Each of the disrupting heads has a plane of symmetry,  wherein the planes  of symmetry of the two disrupting heads are relatively rotated by about 90°.  A fluid emitting end of the fluid supply tube communicates with an irrigation port in a disrupting head so that fluid emitted through the irrigation port, during use,  applies  pressure  to  the  valve  leaflets  to  be disrupted.   The other end of the fluid supply tube is swaged onto a catheter which in turn is coupled to a fluid supply source for the purpose of supplying fluid to the irrigation port.

Abstract: Disclosed is an improved phenol formaldehyde (PF) resin that does not require fillers or extenders and is capable of bonding wafers or veneers having a moisture content of 10% or above.          In the case of veneers exceptional results are obtained when the permeability of the veneer is increased by incising.           The adhesive compositon is prepared by mixing together a caustic solution of a high molecular weight PF resin, a dispersion of PF resin which is characterised in that it can swell in aqueous caustic medium but not go into solution, and a chemical which is capable of reacting with resins in both the continuous and the disperse phase, such as alkylene carbonates or phenol resorcinol formaldehyde (PRF) resins.          Optionally, a component may be used such as borax which is capable of complexing with resins in the continuous and the disperse phase.  The disperse phase is made by converting a solution of a PF resin into a fine particle size particulate form by precipitation, spray drying or freeze drying and partially cross-linking the resin during or subsequent to the formation of the fine particle size dispersion.  The PF resin is partially cross-linked by (a) heat, by (b) acid catalysis, or by (c) a reaction with cross-linking chemicals such as cyclic carbonates or epoxy compounds or by a combination of (a) (b) and (c).           The disperse phase may be made from a PF resin or from a resin in which some of the phenol has been replaced by other phenolic chemicals such as resorcinol, catechol, or kraft lignin.  The chemical capable of reacting with resins in the continuous and the disperse phase may be a cyclic carbonate or a phenol resorcinol resin.           Also disclosed is a wood product produced from veneers having moisture contents at 10% or above and incised to improve their permeability to gases and liquids.

Abstract: LEAK DETECTOR                Abstract of the Disclosure A leak detection system and a method of detecting leaks are disclosed for detecting a leak in a system. including A pump, a dispenser, a conduit communicating the pump and the dispenser, and a valve in the conduit.  The valve includes an electronic flow measurement device for detecting leaks in the system downstream of the device.    The system may be operated by a control circuitry, which indicates a predetermined flow of fluid indicating a leak.  The present invention is also directed to a method of detecting a leak in a system having a fluid pump, a dispenser, a conduit connecting the pump and the dispenser, a valve in the conduit, and an electronic flow detection system in the valve.  The valve is provided with an orifice communicating the conduit with the electronic flow detection system.    The method includes the steps of activating the pump and opening the dispenser to dispense a fluid, and then closing the dispenser while continuing the activation of the pump thereby increasing fluid pressure in the conduit.  The increase in fluid pressure causes the valve to close, thus isolating the pump from the dispenser except for the orifice in the valve.  The electronic fluid detection system senses the flow of fluid through the orifice.

Abstract: A latch assembly for use in combination with slidable doors is disclosed. A rotatable disk is connected to the door so that the plane of the disk is perpendicular to the door and parallel to the direction of door movement. A lock bolt which projects from the door jam is adapted to engage a slot in the disk as the door closes, causing the disk to rotate. As the disk rotates, it slides with respect to a spring loaded latch bolt until the bolt slides through a second slot in the disk, when the door is fully closed. Efforts to effectuate a forced entry of the door cause the resulting forces to be passed primarily between the disk and the lock bolt, while the latch bolt's primary function is to prevent rotation of the disk. Thus, an attempted forced entry will not cause excessive forces to be placed on the latch bolt. The latch bolt is slidably connected to a conventional manually operated garage door handle assembly including a lock.

Granted: 1988-03-10
Abstract: This invention relates to an apparatus and a method for the production of outwardly ribbed, plastic pipes. The apparatus includes a core around which a plasticized material is pressed from a nozzle. A kernel having an essentially constant diameter is positioned at the terminal end of the core for a smooth inner face of the pipe. The outer face of the pipe is ribbed by grooves of axially displaceable chill moulds. The end zone of the kernel is provided for the cooling of the inner face of the pipe. In known apparatuses the grooves of the chill moulds are often filled incompletely and the inner face of the pipe becomes uneven on account of air bubbles, for instance. These disadvantages are avoided by heating an initial zone of the kernel for heating the inner face of the pipe and by shaping the surface of the initial zone to slightly expand conicallly in the production direction.

Abstract: The tool, consisting of a shaft (1) and an insertion end (2), has axially closed longitudinal grooves (4, 5) which are open towards the rear end (3) and which are partially provided with a profiling (7) on the groove base (6). The profiling (7) has stop surfaces (9) acting essentially in the axial direction and it is formed by indentations (8), in which, for example, a lubricant can be arranged. When placing the tool in a receptacle of a drive device, dirt can be scraped off on the stop surfaces (9) and deposited in the indentations (8). In the manufacture of the longitudinal grooves (4, 5), the profiling (7) on the groove base (6) prevents an undesired change in length of the insertion end (2) by means of segments rolling off on the insertion end (2) in the axial direction, and it allows a sharp-edged rolling of the profile.
